【题目】When it comes to the Internet, passwords which people often use are under fire. 1 Research has shown that passwords are not a very good way to protect sensitive information.

People would use some random characters, numbers and symbols. Furthermore, a unique password would be used for every site or application the user uses. Unfortunately, the more complex they become, the more people are likely to forget their passwords. The longer the passwords are, the more easily forgotten they are. 2

Google is trying to kill off the password on Android devices by introducing the Trust API, which does what simple passwords cannot. It gives developers a framework for securing their applications using a number of security systems and metrics (指标)on the device. A Trust Score will be generated based on the metrics the device gathers. 3

The Trust Score will be generated based on both metrics like your device location, face scanning, fingerprint and so on. Taken one at a time, these metrics arc not secure. But taken together, these metrics will help define the real "you".

4 This summer, Google will be running tests with some banks to see if Trust API meets their needs before rolling out to all developers later this year. It may take another year for apps and popular sites to start using the Trust API.

This is a pretty exciting change. Passwords have been around for long and although the security of systems has been improved, the convenience of systems hasn't been improved much. 5 Maybe that never-ending conflict between security and convenience will be able to take a break once the Trust system comes out.

A. Google appears to have the best of them.

B. Actually it's been under fire for a long time.

C. People tend to care more about its advantages.

D. Google has already been testing this on the real world.

E. Google has proved that the system is more convenient.

F. Therefore, they use the same password for each application.

G. It'll allow or refuse your application based on your trust score.

【答案】

1B

2F

3G

4D

5A

【解析】本文主要讲了在互联网时代人们经常用密码来保护自己的隐私,但是复杂的,长的密码又容易遗忘,谷歌正在尝试着引用一个Trust Score来使人们使用起来又方便又安全。

1B 考查对上下文的理解空前的意思是:一提到互联网,人们使用的密码经常遭到抨击。空后的意思是:研究已经表明密码确实不是一个保护个人信息的好方法。所以这里选B(事实上,它已经收到抨击好长时间了。)与上下文一致。

2F 考查对上下文的理解。空前的意思是:密码越长,他们越容易忘记。所以这里选F(所以人们在每一台设备上用相同的密码。)与上下文一致

3G 考查对上下文的理解。空前的意思是:将根据设备收集的指标生成信任分数所以选G(这将以信任分数为基础允许或者拒绝你的设备。与上下文一致

4D 考查对上下文的理解空后的意思是:谷歌将与一些银行进行测试,看看Trust API是否会在今年晚些时候向所有开发人员推出之前满足他们的需求。所以这里选D(谷歌已经在真实的世界里测试了。)与上下文一致

5A 考查对上下文的理解空前的意思是:系统的便利还没有改擅很多。空后的意思是:也许安全和便利之间的无休止的冲突一旦信任系统出来就能够得到缓解所以这里选A(谷歌将会很好的利用他们。)与上下文一致。

【题目】阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
B
Our risk of cancer rises as we age. So it makes sense that the elderly should be routinely screened for new tumors(肿瘤)—or doesn't it?
While such careful tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it's important to consider the health benefits of screening and the costs of routine testing.
In many cases, screening can lead to additional operations to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not cause serious health problems in patients' remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a strong reaction among doctors, patients and advocacy(拥护) groups.
It's hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like a remaining life expectancy.
A recent study suggests that doctors start to make more right decisions about who will truly benefit from screening—especially considering the explosion of the elderly.
It's not an easy guess to make, but one that makes sense for the whole patient. Dr. Otis Brawley said, "Many doctors are ordering these tests purely to protect themselves against medical disputes(纠纷). We need to think about the good use of health care and stop talking about the rationing(定量配给制) of health care."
That means making some difficult decisions with elderly patients and going against the misguided belief that when it comes to health care, more is always better.
(1)Some researchers now think that routine cancer screening for the elderly .
A.adds too much to their medical bills
B.helps contribute to a long life
C.can prevent tumor growth
D.is not always necessary
(2)The underlined word "ingrained" in Paragraph 3 most probably means "".
A.important
B.reliable
C.precious
D.deep-rooted
(3)According to Dr. Otis Brawley, why do many doctors recommend routine screening for cancer?
A.Because they want to get more money from the health care system.
B.Because they want to perform their normal duties actively.
C.Because they want to avoid possible trouble.
D.Because they want their patients to suffer less.
(4)What does the author mainly argue for?
A.Screening tests must be effective and dependable.
B.Old people should be careful about routine cancer screening.
C.Screening increases the chances of detecting certain cancers earlier.
D.Whether old people should go for cancer screening should follow rules.
